The alignment cutting mechanism(s) and the cutting mechanism(s) can be a variety of cutting mechanisms known in the art in which embodiments of the invention could be utilized including, but not limited to, blades, saws, lasers, and high powered water streams.

In embodiments, the cutting tool mechanism includes a housing/frame constructed so that it slides on a pair of vertical rails. Each rail is pressed into a top plate and base plate with a roll pin pressed in through the top plate 29 and the base plate 31. Each rail has a set screwed mechanical lock that can be adjusted with the supplied Allen keys. The drive screw shaft is retained in place by two 5/16 roll pins that are pressed in the housing to capture the drive screw shaft. The drive screw 40 is threaded through a top plate 29. The drive screw shaft has a revolving handle 36 pined onto the drive screw shaft 38.

The blade/cutting positioning mechanism in other embodiments include a drive belt assembly associated with the hand crank assembly which positions the alignment blade to a retractable position, an extended position, and to a desired location of a surface to adjust the saw blade to indicate a desired cut line. FIG. 7 illustrates embodiments for those having the mechanics of the drive system 42, and power source (electrical line 43 (shown in FIG. 8)) and blade friction detecting device 47 (shown in FIG. 8). The cover has been removed to view mechanics of the drive system. A cogged belt transfers the circular motion of the drive cog 44 (shown in FIG. 8) to lower cog where the motion is changed from circular to linear. The drawing further illustrates an embodiment including a scotch arm assembly 18 to change the motion to linear. FIG. 8 illustrates one embodiment showing the spar cutter frame plate 35 without the complete drive belt assembly system in order to see some of the working parts associated with this embodiment. The four studs 46 have been installed for the cover and the left side scotch arm 18 (shown in FIG. 1) axle 48 is in place. Visible are frame fasteners 41 that allow the cutter to swivel from side to side to allow precise cutting of the spar. Also the drawing illustrates the mechanical stops with set screws 40 and a top angle plate 29.

FIGS. 9 A & B illustrate the drive shaft assembly 28. The air motor drive shaft 50 is attached to the motor drive. The drive shaft goes through the air motor 33 adapter then through the drive block and out through the frame 35. The drive cog in this embodiment is driven by a 0.09 square key and is retained in place by a threaded nut.

In embodiments, the blade cutting controlling mechanism includes at least one hand crank assembly, at least one vertical stopping device and at least one set screw to define the boundaries of the cutting area. In most cases the blade(s) further needs a lubricant. When a hand crank assembly is used it lifts the saw blade away from the cutting area. When the alignment blade and the saw blade is utilized they can be configured to be interchangeable. One skilled in the art that the combination of hand crank and saw blade can be replaced with any mechanism that is known in the art to accomplish the desired result and is included within the scope of the invention.

The cutting tool assembly may include at least one regulator assembly or like mechanism to control the cutting process. When a regular assembly is utilized it includes, but is not limited to, an air pressure regulator, a pressure indicator, and a pressure adjuster.

By using the lock pins 56 the cutter is allowed to pivot up to 20° from the horizontal position. There is a socket head set screw 20 that can be adjusted in or out to achieve a desired angle of the cut. The radius arms 54 have been constructed to allow for the angle of the cutter and to achieve a solid vibration free machine action when tightened. There are two large socket head cap screws 20A that are to be tightened when the angle of the tool has been achieved.

FIG. 1 illustrates the cutting tool assembly as a portable kit.

Table 1 is a sample of components included in an embodiment of the invention; however, the kit is not limited to this embodiment and depends on the functions, options, and variations of embodiments of the kit as to one skilled in the art.

TABLE 1 Component of the Kit. Tools: Allen wrench (assorted sizes) Lubricants Extreme Pressure Lube #3 (CAS #647-42-650) Cutting fluid Spar cutter Right hand scotch arm Left hand scotch arm Angle plate assembly Assorted welded saw blades C-Clamps ⅜″-⅜ drive socket ⅜″ × 6″ extension ⅜″ × 8″ ratchet ⅞″ modified socket 8″ adjustable wrench Example of a Cutting Tool Kit Assembly and its Use

The following examples are for illustration purposes only and not to be used to limit any of the embodiments nor its applications. This embodiment is useful for removing damaged areas from a wing spar. In this example, the angle plate assembly would be placed on a surface away from the inner wing. Lock pins and Allen bolts would be installed; however, any fastening device sufficient to secure the angle plate would suffice. The spar cutting tool mechanism is lowered onto the angle plate assembly and the locking pins are installed. The Allen bolts were threaded through the radius arm into the base plate. The slotted plate was placed on top of the spar(s), the set screws were used to level the slotted plate over the damaged spar in the location supplied by the aero engineer (AE). The socket head cap screws were used to tighten the slotted plate to the spars. (Note: It is an object not to scratch the phosphate finish on the inner wing) The spar cutter was lowered onto the slotted plate. The supplied c-clamps 22 (shown in FIG. 1) in the kit were used to fasten the spar cutter to the slotted plate; however, any fastening device sufficient to secure the spar cutter to the slotted plate will suffice. The shaft locking collar was twisted open and the alignment blade was installed. This will establish the exact path the saw blade will traverse in accordance with the AE.

It is to be understood that embodiments of the invention may also include variations including, but not limited to, exchangeable blades held by the same shaft locking collar mechanism, all blades integrated with the cutting tool assembly each blade having their own shaft locking collar mechanism, and all blades removably associated with the cutting assembly tools' shaft locking collar mechanism. It is also understood that each shaft locking collar is adapted to removably receive any desired shape or sized blade(s).

The artisan will move the drive belt up or down to position the alignment blade to its most retracted position. It is understood that any mechanism known in the art can be utilized to align the blades in embodiments of the invention. Once the saw shaft is in the most retracted position the hand crank can be turned (in this example, counterclockwise (CW)) to lower the saw shaft down to the web section of the spar. The drive belt is moved until the saw shaft is in the most extended position. The hand crank is turned to make the alignment blade traverse up and down the indicated cut-line and make adjustments to the saw as necessary. The c-clamps were tightened when the alignment blade followed the indicated cut line. The alignment arm was assembled to scribe the opposite side of the spar. It is also understood that the cutting tool alignment mechanism can be automated or operated manually.

For this example, a titanium sheet was utilized and laid down on the aircraft's carbon fiber inner skin. When using the hand crank, the alignment blade was traversed along the previously indicated area. When the alignment blade touches the titanium sheet there should be slight friction between the titanium sheet and the bottom of the alignment blade. The alignment arm will have scribed a line on the inside of the spar. At this time the set screw is lowered until it touches the titanium sheet with slight friction and the vertical stops are adjusted. The set screws should be loosened on the collar and the collar is slide up until it rests on the bottom of the frame. The set screws should then be tightened.

The saw is to be then raised to allow access to the twistable locking collar. The saw shaft is retracted so that it can be cranked up without touching the widest section of the spar. The locking collar is twisted open and the alignment blade removed. At this time the alignment arm should be unbolted. The locking collar should be twisted back open and the saw blade installed. The artisan will dab a generous portion of the supplied center lube to the exposed section of the saw shaft (if an equivalent lube is available it maybe applied through the zerk fitting). The saw shaft should be thoroughly lubricated. To start the saw, the air pressure regulator should be opened and the pressure set to 65-70 PSI. Once the saw has reached maximum speed, the saw is lowered by turning the hand crank CW. STOP before the blade contacts the spar. Dab a generous amount of cutting fluid on the saw blade and proceed to cut the spar by lowering the saw. When the saw nears the bottom of the spar the artisan will feel the hand crank bottom out and no further travel can be accomplished. At this time the titanium sheet should barely be scratched. The hand crank should be reversed to lift the saw blade away from the spar. When the cutting tool is clear of the damaged spar it can be moved to the next damaged section.

Changing the Scotch Arm Assembly

In this embodiment, a Scotch arm assembly is utilized but any similar or like mechanism can be used to achieve a similar result and this example does not limit the scope of the invention. The C-clamps are to be used when the angle plate assembly is fastened to the A/C. There is a ⅜″-socket wrench, ⅜″×⅜ drive socket, a highly modified ⅞″ ⅜ drive socket, a 6″ extension and 8″ adjustable wrench, and verity of Allen wrenches in this section of the cutouts. When the scotch arm assembly is not in use it is stored in here. There are also modified saw blades in this portable container. The angle plate assembly is located in a pocket constructed to store for transportation or when not in use. The cutting tool assembly is to be stored in this portable container. In one embodiment, a cut out of foam is used to allow easy entry and egress of the tool. FIG. 12 illustrates the slotted plate installed on the A/C. The slotted plate is installed on the A/C. The assembled tool will be placed on the slotted plate and positioned over the damaged area. The C-clamps 22 are used to attach the top angle plate assembly 29 and 31/tool to the slotted plate and to the A/C.

Wing Spar

Although the cutting tool is intended for a variety of uses and functions, the embodiments of the invention are not limited to wing spars and the following is an example of the inventions' use. In a fixed-wing aircraft as shown in FIG. 13, the wing spar 58 is often the main structural member of the wing, running span-wise at right angles (or thereabouts depending on wing sweep) to the fuselage. The spar carries flight loads and the weight of the wings whilst on the ground. Other structural and forming members including ribs may be attached to the spar or spars, with stressed skin construction also sharing the loads where it is used. There may be more than one spar in a wing or none at all; however, where a single spar carries the majority of the forces on it, it is known as the main spar.

Spars are also used in other aircraft aerofoil surfaces including the tailplane and fin which serve a similar function although the loads transmitted may be different to those of a wing spar.

Forces on a Wing Spar

Some of the forces acting on a wing spar include:

Upward bending loads resulting from the wing lift force that supports the fuselage in flight. These forces change in relation to the mass of the aircraft and acceleration due to gravity, and are often offset by carrying fuel in the wings or employing wing-tip-mounted fuel tanks; the Cessna 310 is an example of this design feature.

Downward bending loads whilst stationary on the ground due to the weight of the structure, fuel carried in the wings, and wing-mounted engines if used.

Drag loads dependent on airspeed and inertia.

Rolling inertia loads.

Chordwise twisting loads due to aerodynamic effects at high airspeeds often associated with washout, and the use of ailerons resulting in control reversal. Further twisting loads are induced by changes of thrust settings to underwing-mounted engines.

Many of these loads are reversed abruptly in flight with an aircraft such as the Extra 300 when performing extreme aerobatic maneuvers; the spars of these aircraft are designed to safely withstand great load factors.

Materials and Construction

Some spars have a wooden construction. Early aircraft used spars often carved from solid Spruce or Ash. Several different wooden spar types have been used and experimented with for example spars which are either box-section in form; or laminated spars which are laid up in a jig, and compression glued to retain the wing dihedral. Wooden spars are still being used in light aircraft. A disadvantage of the wooden spar is the deteriorating effect that atmospheric conditions, both dry and wet, and biological threats such as wood-boring insect infestation and fungal attack can have on the component; consequently regular inspections are often mandated to maintain airworthiness. Wood wing spars of multipiece construction usually consist of upper and lower members, called spar caps, and vertical sheet wood members, known as shear webs or more simply webs, that span the distance between the spar caps. Some spars are constructed of metal or metal alloys. FIG. 2 illustrates a metal spar construct.

Basic Metal-Sparred Wing

A typical spar in a general aviation aircraft usually includes a sheet of aluminum known as the spar web, with “L” or “T”-shaped strips known as spar caps welded or riveted to the top and bottom of the sheet to prevent buckling under loads when applied. Larger aircraft using this method of spar construction may have the spar caps sealed to provide integral fuel tanks. Fatigue of metal wing spars has been an identified causal factor in aviation accidents, especially in older aircraft.

A design aspect of the Supermarine Spitfire wing that contributed greatly to its success was an innovative spar boom design, made up of five square concentric tubes which fitted into each other. Two of these booms were linked together by an alloy web, creating a lightweight and very strong main spar. The undercarriage legs were attached to pivot points built into the inner, rear of the main spar and retracted outwards and slightly backwards into wells in the non load-carrying wing structure. The narrow undercarriage track of this aircraft was considered to be an acceptable compromise as it allowed the landing impact loads to be transmitted to the strongest parts of the wing structure.

A version of this spar construction method is also used in the BD-5 which was primarily an aluminum tube of approximately 2 inches (5.1 cm) in diameter, and joined at the wing root with a much larger internal diameter aluminum tube to provide the wing structural integrity.

Geodesic Construction

In aircraft such as the Vickers Wellington, a geodesic wing spar structure was employed which had the advantages of being lightweight and able to withstand heavy battle damage with only partial loss of strength.

Composite Construction

Many modern aircraft use carbon fiber and Kevlar® in their construction, ranging in size from large airliners to small homebuilt aircraft. The increase in strength and reduction in weight compared to the earlier fiberglass-sparred aircraft allows a greater quantity of water ballast to be carried.
